B itlknown; thatl, CHARLES; pm; a:- citizen'rofz the. :United States of America,

" and; resident 20f Plainfield, countyfof 'UnioiigixandrState of NewuJersey, hayeiinventedi certain new and useful Improvements in F ire-Escapes, of which thefollowing'isa Myf invention; relates to improvements in 1 fire; escapes; and particularly to that type thereof; intended; to the erected outside of: a building. "and opposite :a vertlcal row of.- WindowFs thereof; and comprising; a series of platforms or the like mounted to descend; to-

carrying sprocket wheels over. 7, which the ,gethen wi'th =-meansj for regulating the J descenti of*such: platforms and with means flfor returning: such. platforms. for further use,

1+ ,According to the preferred embodiment of my invention, these platforms jare i mounted at suitable intervals upon an =endless -chain conveyer supported r by a" suitable column chain runs.= In connection with the said sprocket chain and the; platforms secured itheretoyl --provide cables movable with the chain and: platforms, which cable's form conv avenientlhand-gripsorQ-rails; fmoVable-Awith 'theehains'and;platforms and=whichfmay be giaspedaby the :persmisdescending; Jon the 30 e:escape,to. give them additional:.security.-
